<!-- INTRODUCTION -->
<h2 id="intro">Introduction</h2>

<p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
    a single database. To accomplish the latter you'll need a properly set up
    MySQL user who can read/write only the desired database. It's up to you to
    look up the appropriate part in the MySQL manual.
</p>

<h3>Currently phpMyAdmin can:</h3>

<ul><li>browse and drop databases, tables, views, columns and indexes</li>
    <li>create, copy, drop, rename and alter databases, tables, columns and
        indexes</li>
    <li>maintenance server, databases and tables, with proposals on server
        configuration</li>
    <li>execute, edit and bookmark any
        <abbr title="structured query language">SQL</abbr>-statement, even
        batch-queries</li>
    <li>load text files into tables</li>
    <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables
        </li>
    <li>export<a href="#footnote_1"><sup>1</sup></a> data to various formats:
        <abbr title="Comma Separated Values">CSV</abbr>,
    <abbr title="Extensible Markup Language">XML</abbr>,
    <abbr title="Portable Document Format">PDF</abbr>,

    title="International Electrotechnical Commission">IEC</abbr> 26300 -
    OpenDocument Text and Spreadsheet,
    <abbr title="Microsoft Word 2000">Word</abbr>,
    and L<sup>A</sup>T<sub><big>E</big></sub>X formats
        </li>
    <li>import data and MySQL structures from OpenDocument spreadsheets, as well as <abbr title="Extensible Markup Language">XML</abbr>, <abbr title="Comma Separated Values">CSV</abbr>, and <abbr title="Server Query Language">SQL</abbr> files</li>
    <li>administer multiple servers</li>
    <li>manage MySQL users and privileges</li>
    <li>check referential integrity in MyISAM tables</li>
    <li>using Query-by-example (QBE), create complex queries automatically
        connecting required tables</li>
    <li>create <abbr title="Portable Document Format">PDF</abbr> graphics of
        your Database layout</li>
    <li>search globally in a database or a subset of it</li>
    <li>transform stored data into any format using a set of predefined
        functions, like displaying BLOB-data as image or download-link
        </li>
    <li>track changes on databases, tables and views</li>
    <li>support InnoDB tables and foreign keys <a href="#faq3_6">(see

    <li>create, edit, call, export and drop stored procedures and functions</li>
    <li>create, edit, export and drop events and triggers</li>
    <li>communicate in <a href="http://www.phpmyadmin.net/home_page/translations.php">62 different languages</a>
        </li>
    <li>synchronize two databases residing on the same as well as remote servers
        <a href="#faq9_1">(see <abbr title="Frequently Asked Questions">FAQ</abbr> 9.1)</a>
    </li>

</ul>

<h4>A word about users:</h4>
<p> Many people have difficulty
    understanding the concept of user management with regards to phpMyAdmin. When
    a user logs in to phpMyAdmin, that username and password are passed directly
    to MySQL. phpMyAdmin does no account management on its own (other than
    allowing one to manipulate the MySQL user account information); all users
    must be valid MySQL users.</p>

<p class="footnote" id="footnote_1">
    <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
    dumps and <abbr title="comma separated values">CSV</abbr> exports if you use
    PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
    (<tt>--with-bz2</tt>). Proper support may also need changes in
    <tt>php.ini</tt>.</p>

<!-- INSTALLATION -->
<h2 id="setup">Installation</h2>

    <li><a href="#setup_script">Setup script usage</a></li>
    <li><a href="#linked-tables">phpMyAdmin configuration storage</a></li>

    <li><a href="#authentication_modes">Using authentication modes</a></li>
</ol>

<p class="important">
    phpMyAdmin does not apply any special security methods to the MySQL database
    server. It is still the system administrator's job to grant permissions on
    the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
    be used for this.
</p>

<p class="important">
    Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
    if you are on a <acronym title="Apple Macintosh">Mac</acronym>
    <abbr title="operating system">OS</abbr> version before
    <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
    <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
    So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
    before uploading them to your server, as PHP seems not to like
    <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
    (&quot;<tt>\r</tt>&quot;).</p>

<h3 id="quick_install">Quick Install</h3>
<ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
    Downloads page. Some kits contain only the English messages,
    others contain all languages in UTF-8 format (this should be fine
    in most situations), others contain all
    languages and all character sets. We'll assume you chose a kit whose
    name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
    </li>
    <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
        <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
        document root. If you don't have direct access to your document root,
        put the files in a directory on your local machine, and, after step 4,
        transfer the directory on your web server using, for example, ftp.</li>
    <li>Ensure that all the scripts have the appropriate owner (if PHP is
        running in safe mode, having some scripts with an owner different
        from the owner of other scripts will be a
        problem). See <a href="#faq4_2">
        <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
        <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
        1.26</a> for suggestions.</li>
    <li>Now you must configure your installation. There are two methods that
        can be used. Traditionally, users have hand-edited a copy of
    <tt>config.inc.php</tt>, but now a wizard-style setup script is
    provided for those who prefer a graphical installation. Creating a
    <tt>config.inc.php</tt> is still a quick way to get started and needed for some advanced features.
        <ul><li>To manually create the file, simply use your text editor to
                create the file <tt>config.inc.php</tt> (you can copy
                <tt>config.sample.inc.php</tt> to get minimal configuration
                file) in the main (top-level) phpMyAdmin directory (the one
                that contains <tt>index.php</tt>).  phpMyAdmin first loads
                <tt>libraries/config.default.php</tt> and then overrides those
                values with anything found in <tt>config.inc.php</tt>. If the
                default value is okay for a particular setting, there is no
                need to include it in <tt>config.inc.php</tt>.  You'll need a
                few directives to get going, a simple configuration may look
                like this:
<pre>
&lt;?php
$cfg['blowfish_secret'] = 'ba17c1ec07d65003';  // use here a value of your choice

$i=0;
$i++;
$cfg['Servers'][$i]['auth_type']     = 'cookie';
?&gt;
</pre>
                Or, if you prefer to not be prompted every time you log in:
<pre>
&lt;?php

$i=0;
$i++;
$cfg['Servers'][$i]['user']          = 'root';
$cfg['Servers'][$i]['password']      = 'cbb74bc'; // use here your password
$cfg['Servers'][$i]['auth_type']     = 'config';
?&gt;
</pre>
                For a full explanation of possible configuration values, see the
                <a href="#config">Configuration Section</a> of this document.</li>
            <li id="setup_script">Instead of manually editing
                <tt>config.inc.php</tt>, you can use the
                <a href="setup/">Setup Script</a>. First you must
                manually create a folder <tt>config</tt> in the phpMyAdmin
                directory. This is a security measure. On a Linux/Unix system you
                can use the following commands:
<pre>
cd phpMyAdmin
mkdir config                        # create directory for saving
chmod o+rw config                   # give it world writable permissions
</pre>
                And to edit an existing configuration, copy it over first:
<pre>
cp config.inc.php config/           # copy current configuration for editing
chmod o+w config/config.inc.php     # give it world writable permissions
</pre>
                On other platforms, simply create the folder and ensure that your
                web server has read and write access to it. <a href="#faq1_26">FAQ
                1.26</a> can help with this.<br /><br />

                Next, open <tt><a href="setup/">setup/</a>
                </tt>in your browser. Note that <strong>changes are not saved to
                disk until explicitly choose <tt>Save</tt></strong> from the
                <i>Configuration</i> area of the screen. Normally the script saves
                the new config.inc.php to the <tt>config/</tt> directory, but if
                the webserver does not have the proper permissions you may see the
                error "Cannot load or save configuration." Ensure that the <tt>
                config/</tt> directory exists and has the proper permissions -
                or use the <tt>Download</tt> link to save the config file locally
                and upload (via FTP or some similar means) to the proper location.<br /><br />

                Once the file has been saved, it must be moved out of the <tt>
                config/</tt> directory and the permissions must be reset, again
                as a security measure:
<pre>
mv config/config.inc.php .         # move file to current directory
chmod o-rw config.inc.php          # remove world read and write permissions
rm -rf config                      # remove not needed directory
</pre>
                Now the file is ready to be used. You can choose to review or edit
                the file with your favorite editor, if you prefer to set some
                advanced options which the setup script does not provide.</li></ul></li>
    <li>If you are using the
        <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
        protect the phpMyAdmin installation directory because using
        config does not require a user to
        enter a password to access the phpMyAdmin installation. Use of an alternate
        authentication method is recommended, for example with
        HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
        <tt>auth_type</tt> cookie or http. See the
        <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
        <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
        information, especially <a href="#faq4_4">
        <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
    <li>Open the <a href="index.php">main phpMyAdmin directory</a>
        in your browser. phpMyAdmin should now display a welcome screen
        and your databases, or a login dialog if using
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
        authentication mode.</li>
    <li>You should deny access to the <tt>./libraries</tt> and
        <tt>./setup/lib</tt> subfolders in your webserver configuration. For
        Apache you can use supplied <a href="#glossary"><i>.htaccess</i></a> file in that folder, for other
        webservers, you should configure this yourself.  Such configuration
        prevents from possible path exposure and cross side scripting
        vulnerabilities that might happen to be found in that code.</li>
    <li>
        It is generally good idea to protect public phpMyAdmin installation
        against access by robots as they usually can not do anything good
        there. You can do this using <code>robots.txt</code> file in root of
        your webserver or limit access by web server configuration, see 
        <a href="#faq1_42"><abbr title="Frequently Asked Questions">FAQ</abbr> 1.42</a>.
    </li>
</ol>

<h3 id="linked-tables">phpMyAdmin configuration storage</h3>

<p> For a whole set of new features (bookmarks, comments,
    <abbr title="structured query language">SQL</abbr>-history,
    tracking mechanism,
    <abbr title="Portable Document Format">PDF</abbr>-generation, column contents
    transformation, etc.) you need to create a set of special tables. Those
    tables can be located in your own database, or in a central database for a
    multi-user installation (this database would then be accessed by the
    controluser, so no other user should have rights to it).</p>

<p> Please look at your <tt>./examples/</tt> directory, where you should find a
    file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
    special attention to <a href="#faq1_23">
    <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>

<p> If you already had this infrastructure and upgraded to MySQL 4.1.2
    or newer, please use <i>./examples/upgrade_tables_mysql_4_1_2+.sql</i>
    and then create new tables by importing <i>./examples/create_tables.sql</i>.</p>

<p> You can use your phpMyAdmin to create the tables for you. Please be aware
    that you may need special (administrator) privileges to create the database
    and tables, and that the script may need some tuning, depending on the
    database name.</p>

<p> After having imported the <i>./examples/create_tables.sql</i> file, you
    should specify the table names in your <i>./config.inc.php</i> file. The
    directives used for that can be found in the <a href="#config">Configuration
    section</a>. You will also need to have a controluser with the proper rights
    to those tables (see section <a href="#authentication_modes">Using
    authentication modes</a> below).</p>

<h3 id="upgrading">Upgrading from an older version</h3>

<p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
    unpacked one. Configuration files from old versions may
    require some tweaking as some options have been changed or removed; in
    particular, the definition of <tt>$cfg['AttributeTypes']</tt> has changed
    so you better remove it from your file and just use the default one.
    For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
    statement that you might find near the end of your configuration file.</p>

<p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
    over <tt>config.inc.php</tt> because the default configuration file
    is version-specific.</p>

<p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
    version 5.x or newer and if you use the phpMyAdmin configuration storage,
    you should run the <abbr title="structured query language">SQL</abbr> script
    found in <tt>examples/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>

<h3 id="authentication_modes">Using authentication modes</h3>

<ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
        authentication modes are recommended in a <b>multi-user environment</b>
        where you want to give users access to their own database and don't want
        them to play around with others.<br />
        Nevertheless be aware that MS Internet Explorer seems to be really buggy
        about cookies, at least till version 6.<br />
        Even in a <b>single-user environment</b>, you might prefer to use
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
        that your user/password pair are not in clear in the configuration file.
        </li>

    <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
        authentication modes are more secure: the MySQL login information does
        not need to be set in the phpMyAdmin configuration file (except possibly
        for the <a href="#controluser">controluser</a>).<br />
        However, keep in mind that the password travels in plain text, unless
        you are using the HTTPS protocol.<br />
        In cookie mode, the password is stored, encrypted with the blowfish
        algorithm, in a temporary cookie.</li>

    <li id="pmausr">Note: this section is only applicable if
        your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />

        For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
        modes, phpMyAdmin needs a controluser that has <b>only</b> the
        <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
        `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
        (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
        `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
        for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
        file under the
        <tt><a href="#cfg_Servers_controluser" class="configrule">
            $cfg['Servers'][$i]['controluser']</a></tt> and
        <tt><a href="#cfg_Servers_controlpass" class="configrule">
            $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
        The following example assumes you want to use <tt>pma</tt> as the
        controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
        only an example: use something else in your file!</b> Input these
        statements from the phpMyAdmin <abbr title="structured query language">SQL
        </abbr> Query window or mysql command&#8211;line client.<br />
        Of course you have to replace <tt>localhost</tt> with the webserver's host
        if it's not the same as the MySQL server's one.

        <pre>
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (
    Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
    Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
    File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
    Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
    Execute_priv, Repl_slave_priv, Repl_client_priv
    ) ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT ON mysql.host TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
    ON mysql.tables_priv TO 'pma'@'localhost';</pre>

        If you want to use the many new relation and bookmark features:

        <pre>
GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
</pre>

        (this of course requires that your <a href="#linked-tables">phpMyAdmin
        configuration storage</a> be set up).  
    <br /></li>

    <li>Then each of the <i>true</i> users should be granted a set of privileges
        on a set of particular databases. Normally you shouldn't give global
        privileges to an ordinary user, unless you understand the impact of those
        privileges (for example, you are creating a superuser).<br />
        For example, to grant the user <i>real_user</i> with all privileges on
        the database <i>user_base</i>:<br />

        <pre>
GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
</pre>

        What the user may now do is controlled entirely by the MySQL user
        management system.<br />
        With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
        authentication mode, you don't need to fill the user/password fields
        inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
        array.</li>
</ul>

<h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

<ul><li>Uses <abbr title="HyperText Transfer Protocol">HTTP</abbr> Basic authentication
        method and allows you to log in as any valid MySQL user.</li>
    <li>Is supported with most PHP configurations. For
        <abbr title="Internet Information Services">IIS</abbr>
        (<abbr title="Internet Server Application Programming Interface">ISAPI</abbr>)
        support using <abbr title="Common Gateway Interface">CGI</abbr> PHP see
        <a href="#faq1_32"><abbr title="Frequently Asked Questions">FAQ</abbr>
        1.32</a>, for using with Apache
        <abbr title="Common Gateway Interface">CGI</abbr> see
        <a href="#faq1_35"><abbr title="Frequently Asked Questions">FAQ</abbr>
        1.35</a>.</li>
    <li>See also <a href="#faq4_4">
        <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a> about not
        using the <a href="#glossary"><i>.htaccess</i></a> mechanism along with
        '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
        mode.</li>
</ul>

<h4>'cookie' authentication mode</h4>

<ul><li>You can use this method as a replacement for the
        <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
        (for example, if you're running
        <abbr title="Internet Information Services">IIS</abbr>).</li>
    <li>Obviously, the user must enable cookies in the browser, but this is
    now a requirement for all authentication modes.</li>
    <li>With this mode, the user can truly log out of phpMyAdmin and log in back
        with the same username.</li>
    <li>If you want to log in to arbitrary server see
        <a href="#AllowArbitraryServer" class="configrule">
        $cfg['AllowArbitraryServer']</a> directive.</li>
    <li>As mentioned in the <a href="#require">requirements</a> section, having
        the <tt>mcrypt</tt> extension will speed up access considerably, but is
        not required.</li>
</ul>

<h4>'signon' authentication mode</h4>

<ul><li>This mode is a convenient way of using credentials from another
    application to authenticate to phpMyAdmin.</li>
    <li>The other application has to store login information into
    session data.</li>
    <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
    section.</li>
</ul>
<h4>'config' authentication mode</h4>

<ul><li>This mode is the less secure one because it requires you to fill the
        <a href="#servers_user" class="configrule">
        $cfg['Servers'][$i]['user']</a> and
        <a href="#servers_user" class="configrule">
        $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
        can read your config.inc.php can discover your username and password).
        <br />
        But you don't need to setup a &quot;controluser&quot; here: using the
        <a href="#servers_only_db" class="configrule">
        $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
    <li>In the <a href="#faqmultiuser">
        <abbr title="Internet service provider">ISP</abbr>
        <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
        is an entry explaining how to protect your configuration file.</li>
    <li>For additional security in this mode, you may wish to consider the Host
        authentication
        <a href="#servers_allowdeny_order" class="configrule">
            $cfg['Servers'][$i]['AllowDeny']['order']</a> and
        <a href="#servers_allowdeny_rules" class="configrule">
            $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
        directives.</li>
    <li>Unlike cookie and http, does not require a user to log in when first
        loading the phpMyAdmin site. This is by design but could allow any
        user to access your installation. Use of some restriction method is
        suggested, perhaps a <a href="#glossary"><i>.htaccess</i></a> file with the
        HTTP-AUTH directive or disallowing incoming HTTP requests at
        one&#8217;s router or firewall will suffice (both of which
        are beyond the scope of this manual but easily searchable with Google).</li>
</ul>
<h4 id="swekey">Swekey authentication</h4>
<p>
The Swekey is a low cost authentication USB key that can be used in
web applications.<br /><br />
When Swekey authentication is activated, phpMyAdmin requires the
users's Swekey to be plugged before entering the login page (currently
supported for cookie authentication mode only). Swekey Authentication is 
disabled by default.<br /><br />
To enable it, add the following line to <tt>config.inc.php</tt>:
</p>
<pre>
$cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';
</pre>
<p>
You then have to create the <tt>swekey.conf</tt> file that will associate
each user with their Swekey Id. It is important to place this file outside
of your web server's document root (in the example, it is located in <tt>/etc</tt>). A self documented sample file is provided 
in the <tt>examples</tt> directory. Feel free to use it with your own 
users' information.<br /><br />
If you want to purchase a Swekey please visit
<a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
since this link provides funding for phpMyAdmin.

        Starting with version 2.3.0, it is advisable to try leaving this
        blank. In most cases phpMyAdmin automatically detects the proper
        setting. Users of port forwarding will need to set PmaAbsoluteUri (<a
        href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1340187&amp;group_id=23067&amp;atid=377409">more info</a>).
        A good test is to browse a table, edit a row and save it. There should
        be an error message if phpMyAdmin is having trouble auto&#8211;detecting
        the correct value. If you get an error that this must be set or if
        the autodetect code fails to detect your path, please post a bug

    <dt id="cfg_PmaNoRelation_DisableWarning">$cfg['PmaNoRelation_DisableWarning'] boolean</dt>
    <dd>Starting with version 2.3.0 phpMyAdmin offers a lot of features to work

        <br />
        If you tried to set this up and it does not work for you, have a look on

        algorithm: you won&#8217;t be prompted for this passphrase. There is
        no maximum length for this secret.<br /><br />
        
        Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
        makes a bit weaker security as this generated secret is stored in
        session and furthermore it makes impossible to recall user name from 
        cookie.</dd>

    <dt id="cfg_Servers">$cfg['Servers'] array</dt>
    <dd>Since version 1.4.2, phpMyAdmin supports the administration of multiple

        from auth and uses empty password for connecting to MySQL. Password
        login is still tried first, but as fallback, no password method is
        tried.</dd>

    </dt>
    <dd>
        If set to a (an array of) database name(s), only this (these) database(s)
        will be shown to the user. Since phpMyAdmin 2.2.1, this/these
        database(s) name(s) may contain MySQL wildcards characters
        (&quot;_&quot; and &quot;%&quot;): if you want to use literal instances
        of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
        <tt>'my_db'</tt>).<br />
        This setting is an efficient way to lower the server load since the
        latter does not need to send MySQL requests to build the available
        database list. But <span class="important">it does not replace the
        privileges rules of the MySQL database server</span>. If set, it just
        means only these databases will be displayed but
        <span class="important">not that all other databases can't be used.</span>
        <br /><br />

        An example of using more that one database:
        <tt>$cfg['Servers'][$i]['only_db'] = array('db1', 'db2');</tt>
        <br /><br />

        As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
        databases in the left frame, so that you can individually arrange your databases.<br />
        If you want to have certain databases at the top, but don't care about the others, you do not
        need to specify all other databases. Use:
        <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>
        instead to tell phpMyAdmin that it should display db3 and db4 on top, and the rest in alphabetic
        order.</dd>

    <dd>Regular expression for hiding some databases from unprivileged users. 
        This only hides them
        from listing, but a user is still able to access them (using, for example,
        the SQL query area). To limit access, use the MySQL privilege system.
        <br /><br />
        For example, to hide all databases starting with the letter &#34;a&#34;, use<br />
        <pre>$cfg['Servers'][$i]['hide_db'] = '^a';</pre>
        and to hide both &#34;db1&#34; and &#34;db2&#34; use <br />
        <pre>$cfg['Servers'][$i]['hide_db'] = '^(db1|db2)$';</pre>

        The creation of a version has two effects:

            <li>phpMyAdmin logs all commands which change the structure and/or data of the table and links these commands with the version number.</li>
        </ul>

        Of course you can view the tracked changes. On the "Tracking" page a complete report is available for every version.
        For the report you can use filters, for example you can get a list of statements within a date range.
        When you want to filter usernames you can enter * for all names or you enter a list of names separated by ','.
        In addition you can export the (filtered) report to a file or to a temporary database.

        If your rule order is set to <tt>'deny,allow'</tt> then the system applies
        all deny rules followed by allow rules. Access is allowed by default. Any
        client which does not match a Deny command or does match an Allow command
        will be allowed access to the server. <br /><br />

        If your rule order is set to <tt>'allow,deny'</tt> then the system
        applies all allow rules followed by deny rules. Access is denied by
        default.  Any client which does not match an Allow directive or does
        match a Deny directive will be denied access to the server.<br /><br />

        If your rule order is set to 'explicit', authorization is
        performed in a similar fashion to rule order 'deny,allow', with the
        added restriction that your host/username combination <b>must</b> be
        listed in the <i>allow</i> rules, and not listed in the <i>deny</i>
        rules. This is the <b>most</b> secure means of using Allow/Deny rules,
        and was available in Apache by specifying allow and deny rules without
        setting any order.<br /><br />

        If you wish to match all users, it is possible to use a <tt>'%'</tt> as

'localnetA' -&gt; SERVER_ADDRESS/8
'localnetB' -&gt; SERVER_ADDRESS/16
'localnetC' -&gt; SERVER_ADDRESS/24

        Having an empty rule list is equivalent to either using

        Please note that this limitation of <abbr title="structured query language">

        not lower than the value of $cfg['LoginCookieValidity'].</dd>

    <dt id="cfg_LoginCookieStore">$cfg['LoginCookieStore'] integer [number of seconds]</dt>

    <dt id="cfg_LeftFrameDBSeparator">$cfg['LeftFrameDBSeparator']
    string or array</dt>
    <dd>The string used to separate the parts of the database name when showing

        and all of them will be used as a separator.</dd>

    <dt id="cfg_LeftFrameTableSeparator">$cfg['LeftFrameTableSeparator'] string</dt>
    <dd>Defines a string to be used to nest table spaces. Defaults to '__'.
        This means if you have tables like 'first__second__third' this will be
        shown as a three-level hierarchy like: first &gt; second &gt; third.
        If set to FALSE or empty, the feature is disabled.  NOTE: You should
        not use this separator at the beginning or end of a

        characters in between.</dd>

    <dt id="cfg_LeftFrameTableLevel">$cfg['LeftFrameTableLevel'] string</dt>
    <dd>Defines how many sublevels should be displayed when splitting
        up tables by the above separator.</dd>

    <dt id="cfg_LeftRecentTable">$cfg['LeftRecentTable'] integer</dt>
    <dd>The maximum number of recently used tables shown in the left navigation
        frame. Set this to 0 (zero) to disable the listing of recent tables.</dd>

    <dt id="cfg_ShowTooltip">$cfg['ShowTooltip'] boolean</dt>
    <dd>Defines whether to display table comment as tool-tip in left frame or
        not.</dd>

    <dt id="cfg_ShowTooltipAliasDB">$cfg['ShowTooltipAliasDB'] boolean</dt>
    <dd>If tool-tips are enabled and a DB comment is set, this will flip the
        comment and the real name. That means that if you have a database called
        'user0001' and add the comment 'MyName' on it, you will see the name
        'MyName' used consequently in the left frame and the tool-tip shows
        the real name of the DB.</dd>

    <dt id="cfg_ShowTooltipAliasTB">$cfg['ShowTooltipAliasTB'] boolean/string</dt>
    <dd>Same as <a href="#cfg_ShowTooltipAliasDB" class="configrule">$cfg['ShowTooltipAliasDB']</a>, except this works for table names.

        When setting this to 'nested', the Alias of the Tablename is only used
        to split/nest the tables according to the
        <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
        directive. So only the folder is called like the Alias, the tablename itself
        stays the real tablename.</dd>

    <dt id="cfg_LeftDisplayLogo">$cfg['LeftDisplayLogo'] boolean</dt>

    <dt id="cfg_LeftDisplayTableFilterMinimum">$cfg['LeftDisplayTableFilterMinimum']
    integer</dt>
    <dd>Defines the minimum number of tables to display a JavaScript filter box above the

    Defaults to <tt>30</tt>. To disable the filter completely some high number
    can be used (e.g. 9999)</dd>

    <dt id="cfg_LeftDisplayServers">$cfg['LeftDisplayServers'] boolean</dt>

        Defaults to FALSE (drop-down).</dd>
    <dt id="cfg_DisplayDatabasesList">$cfg['DisplayDatabasesList'] boolean or text</dt>
    <dd>Defines whether to display database choice in light navigation frame as links
        instead of in a drop-down. Defaults to 'auto' - on main page list is
        shown, when database is selected, only drop down is displayed.</dd>

    <dt id="cfg_LeftDefaultTabTable">$cfg['LeftDefaultTabTable'] string</dt>
    <dd>Defines the tab displayed by default when clicking the small
        icon next to each table name in the navigation panel. Possible
        values: &quot;tbl_structure.php&quot;,

        &quot;tbl_change.php&quot; or &quot;sql.php&quot;.</dd>

    <dt id="cfg_ShowStats">$cfg['ShowStats'] boolean</dt>
    <dd>Defines whether or not to display space usage and statistics about databases
        and tables.<br />
        Note that statistics requires at least MySQL 3.23.3 and that, at this
        date, MySQL doesn't return such information for Berkeley DB tables.</dd>

    <dt><span id="cfg_ShowServerInfo">$cfg['ShowServerInfo'] </span>boolean</dt>
    <dd>Defines whether to display detailed server information on main page.

    <dd>Defines whether to display the &quot;PHP information&quot; and
        &quot;Change password &quot; links and form for creating database or
        not at the starting main (right) frame. This setting
        does not check MySQL commands entered directly.<br /><br />

        Please note that to block the usage of phpinfo() in scripts, you
        have to put this in your <i>php.ini</i>:

        <pre>disable_functions = phpinfo()</pre>

        Also note that enabling the &quot;Change password &quot; link has no
        effect with &quot;config&quot; authentication mode: because of the
        hard coded password value in the configuration file, end users can't
        be allowed to change their passwords.</dd>

    <dt id="cfg_SuggestDBName">$cfg['SuggestDBName'] boolean</dt>
    <dd>Defines whether to suggest a database name on the

    <dt id="cfg_NavigationBarIconic">$cfg['NavigationBarIconic'] string</dt>
    <dd>Defines whether navigation bar buttons and the right panel top menu

        </ul>
        Default is auto.</dd>
    <dd>
        Enabled charset conversion activates a pull-down menu

        <tt>$cfg['Export']['charset']</tt> and <tt>$cfg['Import']['charset']</tt>.
        </dd>

    <dt id="cfg_IconvExtraParams">$cfg['IconvExtraParams'] string</dt>

        <a href="http://www.gnu.org/software/libiconv/documentation/libiconv/iconv_open.3.html">iconv
        documentation</a> for details. By default <code>//TRANSLIT</code> is
        used, so that invalid characters will be transliterated.</dd>

    <dt id="cfg_AvailableCharsets">$cfg['AvailableCharsets'] array</dt>
    <dd>Available character sets for MySQL conversion. You can add your own (any of
        supported by recode/iconv) or remove these which you don't use.
        Character sets will be shown in same order as here listed, so if you
        frequently use some of these move them to the top.</dd>

    <dt id="cfg_TrustedProxies">$cfg['TrustedProxies'] array</dt>
    <dd>Lists proxies and HTTP headers which are trusted for <a

    <dt id="cfg_CheckConfigurationPermissions">$cfg['CheckConfigurationPermissions'] boolean</dt>
    <dd>
    We normally check the permissions on the configuration file to ensure
    it's not world writable. However, phpMyAdmin could be installed on
    a NTFS filesystem mounted on a non-Windows server, in which case the
    permissions seems wrong but in fact cannot be detected. In this case
    a sysadmin would set this parameter to <tt>FALSE</tt>. Default is <tt>TRUE</tt>.

    URL</abbr>s. Default is <code>1000</code>.
    </dd>

    <dt
    id="cfg_DisableMultiTableMaintenance">$cfg['DisableMultiTableMaintenance'] boolean</dt>
    <dd>
    In the database Structure page, it's possible to mark some tables then
    choose an operation like optimizing for many tables. This can slow down
    a server; therefore, setting this to <code>true</code> prevents this kind
    of multiple maintenance operation. Default is <code>false</code>.

        The HeaderFlipType can be set to 'auto', 'css' or 'fake'. When using
        'css' the rotation of the header for horizontalflipped is done via
        CSS. The CSS transformation currently works only in Internet
        Explorer.If set to 'fake' PHP does the transformation for you, but of
        course this does not look as good as CSS. The 'auto' option enables
        CSS transformation when browser supports it and use PHP based one
        otherwise.

        1.11</a>.
        <br /><br />

    If the directory where phpMyAdmin is installed is subject to an
    <tt>open_basedir</tt> restriction, you need to create a
        temporary directory in some directory accessible by the web
        server. However for security reasons, this directory should be outside
        the tree published by webserver. If you cannot avoid having this
        directory published by webserver, place at least an empty
        <tt>index.html</tt> file there, so that directory listing is not
        possible.
        <br /><br />

        This directory should have as strict permissions as possible as the only
        user required to access this directory is the one who runs the
        webserver. If you have root privileges, simply make this user owner of
        this directory and make it accessible only by it:
        <br /><br />

<pre>
chown www-data:www-data tmp
chmod 700 tmp
</pre>

        If you cannot change owner of the directory, you can achieve a similar
        setup using <abbr title="Access Control List">ACL</abbr>:

<pre>
chmod 700 tmp
setfacl -m "g:www-data:rwx" tmp
setfacl -d -m "g:www-data:rwx" tmp
</pre>

        If neither of above works for you, you can still make the directory
        <code>chmod 777</code>, but it might impose risk of other users on
        system reading and writing data in this directory.

        All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
        or icon is always displayed on the left panel. If JavaScript is enabled in
        your browser, a click on this opens a distinct query window, which is
        a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
        changes to display a query box.<br /><br />

        The size of this query window can be customized with
        <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowHeight']</tt>
        - both integers for the size in pixels. Note that normally, those
        parameters will be modified in <tt>layout.inc.php</tt> for the
        theme you are using.<br /><br />

        If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
        from the results page (in the &quot;Showing Rows&quot; section)
        opens the query window and puts the current query
        inside it.  If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
        query in the right panel's query box.
        <br /><br />
        The usage of the JavaScript query window is recommended if you have a
        JavaScript enabled browser. Basic functions are used to exchange quite
        a few variables, so most 4th generation browsers should be capable to
        use that feature. It currently is only tested with Internet Explorer 6
        and Mozilla 1.x.
        <br /><br />
        If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
        to a table, which has to be created by you (see <a
        href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>).  If set to FALSE,
        all your queries will be appended to the form, but only as long as
        your window is opened they remain saved.
        <br /><br />
        When using the JavaScript based query window, it will always get
        updated when you click on a new table/db to browse and will focus if
        you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
        the query window by checking the box "Do not overwrite this query from
        outside the window" below the query textarea. Then you can browse
        tables/databases in the background without losing the contents of the
        textarea, so this is especially useful when composing a query with
        tables you first have to look in. The checkbox will get automatically
        checked whenever you change the contents of the textarea. Please
        uncheck the button whenever you definitely want the query window to
        get updated even though you have made alterations.
        <br /><br />
        If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
        saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
        <br /><br />
        The query window also has a custom tabbed look to group the features.
        Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
        default tab to be used when opening the query window. It can be set to
        either 'sql', 'files', 'history' or 'full'.</dd>

<!-- TRANSFORMATIONS -->
<h2 id="transformations">Transformations</h2>

<ol><li><a href="#transformationsintro">Introduction</a></li>
    <li><a href="#transformationshowto">Usage</a></li>
    <li><a href="#transformationsfiles">File structure</a></li>
</ol>

<h3 id="transformationsintro">1. Introduction</h3>

<p> To enable transformations, you have to setup the <tt>column_info</tt> table
    and the proper directives. Please see the <a href="#config">Configuration
    section</a> on how to do so.</p>

<p> You can apply different transformations to the contents of each column. The
    transformation will take the content of each column and transform it with
    certain rules defined in the selected transformation.</p>

<p> Say you have a column 'filename' which contains a filename. Normally you would
    see in phpMyAdmin only this filename. Using transformations you can transform
    that filename into a HTML link, so you can click inside of the phpMyAdmin
    structure on the column's link and will see the file displayed in a new browser
    window. Using transformation options you can also specify strings to
    append/prepend to a string or the format you want the output stored in.</p>

<p> For a general overview of all available transformations and their options,
    you can consult your
    <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
    installation.</p>

<p> For a tutorial on how to effectively use transformations, see our
    <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
    the official phpMyAdmin homepage.</p>

<h3 id="transformationshowto">2. Usage</h3>

<p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
    clicking on the 'Structure' link for a table). There click on
    &quot;Change&quot; (or change icon) and there you will see three new
    fields at
    the end of the line. They are called 'MIME-type', 'Browser transformation' and
    'Transformation options'.</p>

    <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
    that corresponds to the column's contents. Please note that
        transformations are inactive as long as no MIME-type is selected.</li>

    <li>The field 'Browser transformation' is a drop-down field. You can choose from a
        hopefully growing amount of pre-defined transformations. See below for information on
        how to build your own transformation.<br />

        There are global transformations and mimetype-bound transformations. Global transformations
        can be used for any mimetype. They will take the mimetype, if necessary, into regard.
        Mimetype-bound transformations usually only operate on a certain mimetype. There are
        transformations which operate on the main mimetype (like 'image'), which will most likely
        take the subtype into regard, and those who only operate on a
        specific subtype (like 'image/jpeg').<br />

        You can use transformations on mimetypes for which the function was not defined for. There
        is no security check for you selected the right transformation, so take care of what the
        output will be like.</li>

    <li>The field 'Transformation options' is a free-type textfield. You have to enter
        transform-function specific options here. Usually the transforms can operate with default
        options, but it is generally a good idea to look up the overview to see which options are
        necessary.<br />

        Much like the ENUM/SET-Fields, you have to split up several options using the format
        'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
        parsed as an array, leaving the first value the first element in the array, and so
        forth.<br />

        If you want to specify a MIME character set you can define it in the transformation_options.
        You have to put that outside of the pre-defined options of the specific mime-transform,
        as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
        for which you can specify 2 options and you want to append a character set, enter "'first
        parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
        the parameters: "'','','charset=us-ascii'".</li>
</ul>

<h3 id="transformationsfiles">3. File structure</h3>

<p> All mimetypes and their transformations are defined through single files in
    the directory 'libraries/transformations/'.</p>

<p> They are stored in files to ease up customization and easy adding of new
    transformations.</p>

<p> Because the user cannot enter own mimetypes, it is kept sure that transformations
    always work. It makes no sense to apply a transformation to a mimetype the
    transform-function doesn't know to handle.</p>

<p> One can, however, use empty mime-types and global transformations which should work
    for many mimetypes. You can also use transforms on a different mimetype than what they where built
    for, but pay attention to option usage as well as what the transformation does to your
    column.</p>

<p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
    any other transform function and provides some basic functions.</p>

<p> There are 5 possible file names:</p>

<ol><li>A mimetype+subtype transform:<br /><br />

        <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />

        Please not that mimetype and subtype are separated via '_', which shall
        not be contained in their names. The transform function/filename may
        contain only characters which cause no problems in the file system as
        well as the PHP function naming convention.<br /><br />

        The transform function will the be called
        '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />

        <b>Example:</b><br /><br />

        <tt>text_html__formatted.inc.php</tt><br />
        <tt>PMA_transform_text_html__formatted()</tt></li>

    <li>A mimetype (w/o subtype) transform:<br /><br />

        <tt>[mimetype]__[transform].inc.php</tt><br /><br />

        Please note that there are no single '_' characters.
        The transform function/filename may contain only characters which cause
        no problems in the file system as well as the PHP function naming
        convention.<br /><br />

        The transform function will the be called
        '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />

        <b>Example:</b><br /><br />

        <tt>text__formatted.inc.php</tt><br />
        <tt>PMA_transform_text__formatted()</tt></li>

    <li>A mimetype+subtype without specific transform function<br /><br />

        <tt>[mimetype]_[subtype].inc.php</tt><br /><br />

        Please note that there are no '__' characters in the filename. Do not
        use special characters in the filename causing problems with the file
        system.<br /><br />

        No transformation function is defined in the file itself.<br /><br />

        <b>Example:</b><br /><br />

        <tt>text_plain.inc.php</tt><br />
        (No function)</li>

    <li>A mimetype (w/o subtype) without specific transform function<br /><br />

        <tt>[mimetype].inc.php</tt><br /><br />

        Please note that there are no '_' characters in the filename. Do not use
        special characters in the filename causing problems with the file system.
        <br /><br />

        No transformation function is defined in the file itself.<br /><br />

        <b>Example:</b><br /><br />

        <tt>text.inc.php</tt><br />
        (No function)</li>

    <li>A global transform function with no specific mimetype<br /><br />

        <tt>global__[transform].inc.php</tt><br /><br />

        The transform function will the be called
        '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />

        <b>Example:</b><br /><br />

        <tt>global__formatted</tt><br />
        <tt>PMA_transform_global__formatted()</tt></li>
</ol>

<p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
    transform function.</p>

<p> All filenames containing no '__' in themselves are not shown as valid transform
    functions in the dropdown.</p>

<p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
    function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
    without a transform function.</p>

<p> To create a new transform function please see
    <tt>libraries/transformations/template_generator.sh</tt>.
    To create a new, empty mimetype please see
    <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>

<p> A transform function always gets passed three variables:</p>

<ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
        you want to transform.</li>
    <li><b>$options</b> - Contains any user-passed options to a transform function
        as an array.</li>
    <li><b>$meta</b> - Contains an object with information about your column.
        The data is drawn from the output of the
        <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
        function. This means, all object properties described on the
        <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
        available in this variable and can be used to transform a column accordingly
        to unsigned/zerofill/not_null/... properties.<br />
        The $meta-&gt;mimetype variable contains the original MIME-type of the
        column (i.e. 'text/plain', 'image/jpeg' etc.)</li>
</ol>

<p> Additionally you should also provide additional function to provide 
    information about the transformation to the user. This function should
    have same name as transformation function just with appended
    <code>_info</code> suffix. This function accepts no parameters and returns
    array with information about the transformation. Currently following keys
    can be used:
</p>
<dl>
    <dt><code>info</code></dt>
    <dd>Long description of the transformation.</dd>
</dl>

<p> These features are based on the <tt>gzencode()</tt> and <tt>bzcompress()</tt>
    PHP functions to be more independent of the platform (Unix/Windows, Safe Mode

<p> Your uploaded file is saved by PHP in the &quot;upload dir&quot;, as
    defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
    the system default is <i>/tmp</i>).<br />
    We recommend the following setup for Apache servers running in safe mode,
    to enable uploads of files while being reasonably secure:</p>

<ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
    <li>give ownership to the Apache server's user.group:
        <tt>chown apache.apache /tmp/php</tt></li>
    <li>give proper permission: <tt>chmod 600 /tmp/php</tt></li>

<p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir

    configure it as <a href="#cfg_TempDir" class="configrule">$cfg['TempDir']</a>.

<p> In previous MySQL versions, the <tt>User</tt> and <tt>Password</tt>columns

<h4 id="faq1_16">
    <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
    <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
</h4>

<p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
    problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
    to take advantage of the new import features.</p>

<p> The first things to check (or ask your host provider to check) are the
    values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
    <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
    All of these three settings limit the maximum size of data that can be
    submitted and handled by PHP. One user also said that
    <tt>post_max_size</tt>
    and <tt>memory_limit</tt> need to be larger than <tt>upload_max_filesize</tt>.<br /> <br />

    There exist several workarounds if your upload is too big or your
    hosting provider is unwilling to change the settings:</p>

<ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
        feature. This allows one to
        upload a file to the server via scp, ftp, or your favorite file transfer
        method. PhpMyAdmin is then able to import the files from the temporary
        directory. More information is available in the <a href="#config">Configuration
        section</a> of this document.</li>
    <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
        BigDump</a>) to split the files before uploading. We cannot support this
        or any third party applications, but are aware of users having success
        with it.</li>
    <li>If you have shell (command line) access, use MySQL to import the files
        directly. You can do this by issuing the &quot;source&quot; command from
        within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
</ul>

<h4 id="faq1_17">
    <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
    support?</a></h4>

<p> Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For 
    older MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can 
    connect to your MySQL server using PHP's classic
    <a href="http://php.net/mysql">MySQL extension</a> as well as the
    <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
    is available in PHP 5.0. The latter one should be used unless you have a
    good reason not to do so.<br />
    When compiling PHP, we strongly recommend that you manually link the MySQL
    extension of your choice to a MySQL client library of at least the same
    minor version since the one that is bundled with some PHP distributions is
    rather old and might cause problems <a href="#faq1_17a">
        (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.<br /><br />
    <a href="http://mariadb.org/">MariaDB</a> is also supported
    (versions 5.1 and 5.2 were tested).<br /><br />
    Since phpMyAdmin 3.5 <a href="http://www.drizzle.org/">Drizzle</a> is supported.
    </p>

<h5 id="faq1_17a">
    <a href="#faq1_17a">1.17a I cannot connect to the MySQL server. It always returns the error
    message, &quot;Client does not support authentication protocol requested
    by server; consider upgrading MySQL client&quot;</a></h5>

<p> You tried to access MySQL with an old MySQL client library. The version of
    your MySQL client library can be checked in your phpinfo() output.
    In general, it should have at least the same minor version as your server
    - as mentioned in <a href="#faq1_17">
    <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />

    This problem is generally caused by using MySQL version 4.1 or newer. MySQL
    changed the authentication hash and your PHP is trying to use the old method.
    The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
    with the proper client library to match your MySQL installation. Your
    chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.
    More information (and several workarounds) are located in the
    <a href="http://dev.mysql.com/doc/mysql/en/old-client.html">MySQL Documentation</a>.

<h4 id="faqmysql">
    <a href="#faqmysql">1.20 I receive the error &quot;cannot load MySQL extension, please
    check PHP Configuration&quot;.</a></h4>

<p> To connect to a MySQL server, PHP needs a set of MySQL functions called
    &quot;MySQL extension&quot;. This extension may be part of the PHP
    distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
    name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
    to load the extension but failed.<br /><br />

    Usually, the problem is solved by installing a software package called
    &quot;PHP-MySQL&quot; or something similar.</p>

<h4 id="faq1_22">
    <a href="#faq1_22">1.22 I don't see the &quot;Location of text file&quot; field,

    <a href="#faq1_23">1.23 I'm running MySQL on a Win32 machine. Each time I create

<p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
    defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
    this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
    Just edit your <tt>my.ini</tt> file that should be located in your Windows
    directory and add the following line to the group [mysqld]:</p>

<pre>set-variable = lower_case_table_names=0</pre>

<p> Next, save the file and restart the MySQL service. You can always check the
    value of this directive using the query</p>

<pre>SHOW VARIABLES LIKE 'lower_case_table_names';</pre>

<pre>
# mod_gzip_item_include file \.php$

<p> This is a permission problem. Right-click on the phpmyadmin folder

<p> This can happen due to a MySQL bug when having database / table names with

    To fix this, turn off this directive, convert all database and table names
    to lower case and turn it on again. Alternatively, there's a bug-fix
    available starting with MySQL&nbsp;3.23.56 / 4.0.11-gamma.</p>

<h4 id="faq1_37">
    <a href="#faq1_37">1.37 I run phpMyAdmin on cluster of different machines and
    password encryption in cookie auth doesn't work.</a></h4>

<p> If your cluster consist of different architectures, PHP code used for

<h4 id="faq1_38">
    <a href="#faq1_38">1.38 Can I use phpMyAdmin on a server on which Suhosin is enabled?</a></h4>

<p> Yes but the default configuration values of Suhosin are known to cause 
    problems with some operations, for example editing a table with many
    columns and no primary key or with textual primary key.
</p>
<p>
    Suhosin configuration might lead to malfunction in some cases and it can
    not be fully avoided as phpMyAdmin is kind of application which needs to
    transfer big amounts of columns in single HTTP request, what is something
    what Suhosin tries to prevent. Generally all
    <code>suhosin.request.*</code>, <code>suhosin.post.*</code> and
    <code>suhosin.get.*</code> directives can have negative effect on
    phpMyAdmin usability. You can always find in your error logs which limit
    did cause dropping of variable, so you can diagnose the problem and adjust
    matching configuration variable.
</p>
<p>
    The default values for most Suhosin configuration options will work in most 
    scenarios, however you might want to adjust at least following parameters:
</p>

<ul>
    <li><a href="http://www.hardened-php.net/suhosin/configuration.html#suhosin.request.max_vars">suhosin.request.max_vars</a> should be increased (eg. 2048)</li>

<p>Note: if the backend url looks like http://host/~user/phpmyadmin,

    connect to local MySQL server through socket '/tmp/mysql.sock'
    (111) ...&quot; is displayed. What can I do?</a></h4>

<p> For RedHat users, Harald Legner suggests this on the mailing list:</p>

<p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
    In your <i>php.ini</i> you will find a line</p>

<pre>mysql.default_socket = /tmp/mysql.sock</pre>

<p> change it to</p>

<pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>

<p> Then restart apache and it will work.</p>

<p> Here is a fix suggested by Brad Ummer:</p>

<ul><li>First, you need to determine what socket is being used by MySQL.<br />
        To do this, telnet to your server and go to the MySQL bin directory. In
        this directory there should be a file named <i>mysqladmin</i>. Type
        <tt>./mysqladmin variables</tt>, and this should give you a bunch of
        info about your MySQL server, including the socket
        (<i>/tmp/mysql.sock</i>, for example).</li>
    <li>Then, you need to tell PHP to use this socket.<br /> To do this in
        phpMyAdmin, you need to complete the  socket information in the
        <i>config.inc.php</i>.<br />
        For example:
        <a href="#cfg_Servers_socket" class="configrule">
        $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
        <br /><br />

        Please also make sure that the permissions of this file allow to be readable
        by your webserver (i.e. '0755').</li>
</ul>

<p> Have also a look at the
    <a href="http://dev.mysql.com/doc/en/can-not-connect-to-server.html">
         corresponding section of the MySQL documentation</a>.</p>

<p> When you are using a port on your localhost, which you redirect via
    port-forwarding to another host, MySQL is not resolving the localhost
    as expected.<br />
    Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
    MySQL (the command line tool <code>mysql</code> as well) always tries to use the socket
    connection for speeding up things. And that doesn't work in this configuration

<h4 id="faqthemes"><a href="#faqthemes">2.7 Using and creating themes</a></h4>

<p> Themes are configured with
    <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>,
    <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
    <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
    <br />
    Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
    should not delete the directory &quot;original&quot; or its underlying
    structure, because this is the system theme used by phpMyAdmin.
    &quot;original&quot; contains all images and styles, for backwards
    compatibility and for all themes that would not include images or css-files.
    <br /><br />

    If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
    is enabled, you can select your favorite theme on the main page. Your
    selected theme will be stored in a cookie.<br /><br /></p>

<p> To create a theme:</p>

<ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
        <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
        (by default <tt>themes</tt>)</li>
    <li>copy the files and directories from &quot;original&quot; to
        &quot;your_theme_name&quot;</li>
    <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
    <li>put your new images in &quot;your_theme_name/img&quot;</li>
    <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
    <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
        contain your chosen theme name, that will be visible in user interface</li>
    <li>make a new screenshot of your theme and save it under
        &quot;your_theme_name/screen.png&quot;</li>
</ul>

<p> In theme directory there is file <tt>info.inc.php</tt> which contains
    theme verbose name, theme generation and theme version. These versions and
    generations are enumerated from 1 and do not have any direct dependence on
    phpMyAdmin version. Themes within same generation should be backwards
    compatible - theme with version 2 should work in phpMyAdmin requiring
    version 1. Themes with different generation are incompatible.</p>

<p> If you do not want to use your own symbols and buttons, remove the
    directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
    use the default icons and buttons (from the system-theme &quot;original&quot;).

    Also, you should note the fact that phpMyAdmin will use the size of the largest item in any given column as the column size for the appropriate type. If you 
    know you will be adding larger items to that column then you should manually adjust the column sizes accordingly. This is done for the sake of efficiency.

    <a href="#faq4_1">4.1 I'm an <abbr title="Internet service provider">ISP</abbr>. Can I setup one central copy of phpMyAdmin or do I
    need to install it for each customer.
</a></h4>
<p>
    Since version 2.0.3, you can setup a central copy of phpMyAdmin for all
    your users. The development of this feature was kindly sponsored by
    NetCologne GmbH.
    This requires a properly setup MySQL user management and phpMyAdmin
    <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication. See the install section on
    &quot;Using <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication&quot;.

<h4 id="faq4_2">
    <a href="#faq4_2">4.2 What's the preferred way of making phpMyAdmin secure against evil
    access.
</a></h4>
<p>
    This depends on your system.<br />
    If you're running a server which cannot be accessed by other people, it's
    sufficient to use the directory protection bundled with your webserver
    (with Apache you can use <a href="#glossary"><i>.htaccess</i></a> files, for example).<br />
    If other people have telnet access to your server, you should use
    phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.
    <br /><br />
    Suggestions:
</p>
<ul>
    <li>
        Your <i>config.inc.php</i> file should be <tt>chmod 660</tt>.
    </li>
    <li>
        All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
        is a user whose password is only known to you, and apache is the
        group under which Apache runs.
    </li>
    <li>
        Follow security recommendations for PHP and your webserver.
    </li>
</ul>

<h4 id="faq4_3">
    <a href="#faq4_3">4.3 I get errors about not being able to include a file in

</a></h4>
<p>
    Check <i>php.ini</i>, or ask your sysadmin to check it. The
    <tt>include_path</tt> must contain &quot;.&quot; somewhere in it, and
    <tt>open_basedir</tt>, if used, must contain &quot;.&quot; and
    &quot;./lang&quot; to allow normal operation of phpMyAdmin.
</p>

<h4 id="faq4_4">
    <a href="#faq4_4">4.4 phpMyAdmin always gives &quot;Access denied&quot; when using <abbr title="HyperText Transfer Protocol">HTTP</abbr>

<p> This could happen for several reasons:</p>

<ul><li><a href="#cfg_Servers_controluser" class="configrule">$cfg['Servers'][$i]['controluser']</a>
        and/or
        <a href="#cfg_Servers_controlpass" class="configrule">$cfg['Servers'][$i]['controlpass']</a>
        are wrong.</li>
    <li>The username/password you specify in the login dialog are invalid.</li>
    <li>You have already setup a security mechanism for the
        phpMyAdmin-directory, eg. a <a href="#glossary"><i>.htaccess</i></a> file. This would interfere with
        phpMyAdmin's authentication, so remove it.</li>
</ul>

<h4 id="faq4_5">
    <a href="#faq4_5">4.5 Is it possible to let users create their own databases?</a></h4>

<p> Starting with 2.2.5, in the user management page, you can enter a wildcard
    database name for a user (for example &quot;joe%&quot;),
    and put the privileges you want.  For example,
    adding <tt>SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER</tt>
    would let a user create/manage his/her database(s).</p>

<h4 id="faq4_6">
    <a href="#faq4_6">4.6 How can I use the Host-based authentication additions?</a></h4>

<p> If you have existing rules from an old <a href="#glossary"><i>.htaccess</i></a> file, you can take them
    and add a username between the <tt>'deny'</tt>/<tt>'allow'</tt> and
    <tt>'from'</tt> strings. Using the username wildcard of <tt>'%'</tt> would
    be a major benefit here if your installation is suited to using it. Then
    you can just add those updated lines into the
    <a href="#cfg_Servers_AllowDeny_rules" class="configrule">
        $cfg['Servers'][$i]['AllowDeny']['rules']</a> array.</p>

<p> If you want a pre-made sample, you can try this fragment. It stops the
    'root' user from logging in from any networks other than the private
    network <abbr title="Internet Protocol">IP</abbr> blocks.</p>

<pre>
//block root from logging in except from the private networks
$cfg['Servers'][$i]['AllowDeny']['order'] = 'deny,allow';
$cfg['Servers'][$i]['AllowDeny']['rules'] = array(
    'deny root from all',
    'allow root from localhost',
    'allow root from 10.0.0.0/8',
    'allow root from 192.168.0.0/16',
    'allow root from 172.16.0.0/12',
    );
</pre>

<h4 id="faq4_7">
    <a href="#faq4_7">4.7 Authentication window is displayed more than once, why?</a></h4>

<p> This happens if you are using a <abbr title="Uniform Resource Locator">URL</abbr> to start phpMyAdmin which is
    different than the one set in your
    <a href="#cfg_PmaAbsoluteUri" class="configrule">$cfg['PmaAbsoluteUri']</a>.

    while a domain name is defined in the config file.</p>

<h4 id="faq4_8">
    <a href="#faq4_8">4.8 Which parameters can I use in the URL that starts phpMyAdmin?</a></h4>

<p>When starting phpMyAdmin, you can use the <tt>db</tt>, <tt>pma_username</tt>, <tt>pma_password</tt> and <tt>server</tt> parameters. This last one can contain either the numeric host index (from <tt>$i</tt> of the configuration file) or one of the host names present in the configuration file. Using <tt>pma_username</tt> and <tt>pma_password</tt> has been tested along with the usage of 'cookie' <tt>auth_type</tt>.</p>

    <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
<p>
    First the configuration variables &quot;relation&quot;,
    &quot;table_coords&quot; and &quot;pdf_pages&quot; have to be filled in.
    <br /><br />
    Then you need to think about your schema layout. Which tables will go on
    which pages?
</p>
<ul>
    <li>Select your database in the left frame.</li>
    <li>Choose &quot;Operations&quot; in the navigation bar at the top.</li>
    <li>Choose &quot;Edit <abbr title="Portable Document Format">PDF</abbr>
        Pages&quot; near the bottom of the page.</li>
    <li>Enter a name for the first <abbr title="Portable Document Format">PDF</abbr>
        page and click Go. If you like, you
        can use the &quot;automatic layout,&quot; which will put all your
        linked tables onto the new page.</li>
    <li>Select the name of the new page (making sure the Edit radio button
        is selected) and click Go.</li>
    <li>Select a table from the list, enter its coordinates and click Save.<br />
        Coordinates are relative; your diagram will
        be automatically scaled to fit the page. When initially placing tables
        on the page, just pick any coordinates -- say, 50x50. After clicking
        Save, you can then use the <a href="#wysiwyg">graphical editor</a> to
        position the element correctly.</li>
    <li>When you'd like to look at your <abbr title="Portable Document Format">PDF</abbr>,
        first be sure to click the Save
        button beneath the list of tables and coordinates, to save any changes
        you made there. Then scroll all the way down, select the
        <abbr title="Portable Document Format">PDF</abbr> options
        you want, and click Go.</li>
    <li>Internet Explorer for Windows may suggest an incorrect filename when
        you try to save a generated <abbr title="Portable Document Format">PDF</abbr>.
        When saving a generated <abbr title="Portable Document Format">PDF</abbr>, be
        sure that the filename ends in &quot;.pdf&quot;, for example
        &quot;schema.pdf&quot;. Browsers on other operating systems, and other
        browsers on Windows, do not have this problem.</li>
</ul>

<p> If you do not put a backslash before the underscore, this is a wildcard
    grant, and the underscore means &quot;any character&quot;. So, if the
    database name is &quot;john_db&quot;, the user would get rights to john1db,
    john2db ...<br /><br />

    If you put a backslash before the underscore, it means that the database
    name will have a real underscore.</p>

<p><b>Structure:</b></p>

<ul><li>&quot;Add DROP TABLE&quot; will add a line telling MySQL to
        <a href="http://dev.mysql.com/doc/mysql/en/drop-table.html">drop the table</a>,
        if it already exists during the import. It does NOT drop the table after
        your export, it only affects the import file.</li>
    <li>&quot;If Not Exists&quot; will only create the table if it doesn't exist.
        Otherwise, you may get an error if the table name exists but has a
        different structure.</li>
    <li>&quot;Add AUTO_INCREMENT value&quot; ensures that AUTO_INCREMENT value
        (if any) will be included in backup.</li>
    <li>&quot;Enclose table and column names with backquotes&quot; ensures that
        column and table names formed with special characters are protected.</li>
    <li>&quot;Add into comments&quot; includes column comments, relations, and MIME
        types set in the pmadb in the dump as
        <abbr title="structured query language">SQL</abbr> comments (<i>/* xxx */</i>).
       </li>
</ul>

<p><b>Data:</b></p>

<ul><li>&quot;Complete inserts&quot; adds the column names on every INSERT
        command, for better documentation (but resulting file is bigger).</li>
    <li>&quot;Extended inserts&quot; provides a shorter dump file by using only
        once the INSERT verb and the table name.</li>
    <li>&quot;Delayed inserts&quot; are best explained in the
        <a href="http://dev.mysql.com/doc/mysql/en/insert-delayed.html">MySQL manual</a>.
       </li>
    <li>&quot;Ignore inserts&quot; treats errors as a warning instead. Again,
        more info is provided in the
        <a href="http://dev.mysql.com/doc/mysql/en/insert.html">MySQL manual</a>,

        inserted rather than causing the entire statement to fail.</li>
</ul>

<h4 id="faq6_13">
    <a href="#faq6_13">6.13 I would like to create a database with a dot

<p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;
    is the normal way to reference a database and table name. Worse, MySQL
    will usually let you create a database with a dot, but then you cannot
    work with it, nor delete it.</p>

<h4 id="faqsqlvalidator">
    <a href="#faqsqlvalidator">6.14 How do I set up the
    <abbr title="structured query language">SQL</abbr> Validator?</a></h4>

<p> 
    To use SQL Validator, you need PHP with 
    <abbr title="Extensible Markup Language">XML</abbr>,
    <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
    <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
    In addition you need a <abbr title="Simple Object Access
    Protocol">SOAP</abbr> support, either as a PHP extension or as a PEAR SOAP
    module.
</p>

<p>
    To install <abbr title="PHP Extension and Application
    Repository">PEAR</abbr> <abbr title="Simple Object Access
    Protocol">SOAP</abbr> module, run <tt>"pear install Net_Socket Net_URL

    usage.
</p>

<p>
    If you use the Validator, you should be aware that any
    <abbr title="structured query language">SQL</abbr> statement you
    submit will be stored anonymously (database/table/column names,

    it, but MySQL says &quot;BLOB column '...' used in key specification without
    a key length&quot;.</a></h4>

<p> The right way to do this, is to create the column without any indexes,
    then display the table structure and use the &quot;Create an index&quot;
    dialog. On this page, you will be able to choose your BLOB column, and
    set a size to the index, which is the condition to create an index on
    a BLOB column.</p>

<h4 id="faq6_16">
    <a href="#faq6_16">6.16 How can I simply move in page with plenty

<h4 id="faq6_17">
    <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
    WTF is this feature then useful for?</a></h4>

<p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
    on them. Otherwise you could just put a comment on the column. Because entering
    your own mimetype will cause serious syntax checking issues and validation,
    this introduces a high-risk false-user-input situation. Instead you have to
    initialize mimetypes using functions or empty mimetype definitions.<br />
    Plus, you have a whole overview of available mimetypes. Who knows all those
    mimetypes by heart so he/she can enter it at will?</p>

<h4 id="faqbookmark">
    <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
    can't I see any bookmarks below the query box? What is this variable for?
</a></h4>

<p> Any query you have executed can be stored as a bookmark on the page where the
    results are displayed. You will find a button labeled 'Bookmark this query'
    just at the end of the page.<br />
    As soon as you have stored a bookmark, it is related to the database you run
    the query on. You can now access a bookmark dropdown on each page, the query
    box appears on for that database.<br /><br />

    Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
    Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
    which is put into the <i>value</i> input box on the query box page will
    replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
    aware of that you HAVE to create a valid query, otherwise your query won't be
    even able to be stored in the database.<br />
    Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
    for your query will remain the way it is, but will be stripped of the /**/
    chars. So you can use:<br /><br />

    <code>/*, [VARIABLE] AS myname */</code><br /><br />

    which will be expanded to<br /><br />

    <code>, VARIABLE as myname</code><br /><br />

    in your query, where VARIABLE is the string you entered in the input box. If
    an empty string is provided, no replacements are made.<br /><br />

    A more complex example. Say you have stored this query:<br /><br />
    <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
    <br /><br />

    Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
    the full query will be:<br /><br />

    <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
    <br /><br />

    You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query (that is, multiple occurrences of the <i>same</i> variable).<br />
    <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
    spaces inserted there
    will be later also inserted as spaces in your query and may lead to unexpected
    results especially when
    using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
    Your initial query which is going to be stored as a bookmark has to yield at
    least one result row so
    you can store the bookmark. You may have that to work around using well
    positioned &quot;/**/&quot; comments.</p>

    enable users to see all the database names.

<p> You have to setup appropriate links between the tables, and also
    setup the &quot;display column&quot; in the foreign table. See
    <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
    6.6</a> for an example. Then, if there are 100 values or less in the
    foreign table, a drop-down list of values will be available.
    You will see two lists of values, the first list containing the key
    and the display column, the second list containing the display column 
    and the key. The reason for this is to be able to type the first
    letter of either the key or the display column.<br /><br />

    For 100 values or more, a distinct window will appear, to browse foreign
    key values and choose one. To change the default limit of 100, see

<p> For general information about BLOB streaming on MySQL, visit <a href="http://blobstreaming.org">blobstreaming.org</a>. You need the following components:</p>
<ul>
    <li>PBMS BLOB Streaming Daemon for MySQL (0.5.15 or later)</li>
    <li>Streaming enabled PBXT Storage engine for MySQL (1.0.11-6 or

    <li>PBMS PHP Extension for MySQL (0.1.1 or later)</li>
</ul>

<p>Here are details about configuration and operation:</p>

<ol>
    <li>In <tt>config.inc.php</tt> your host should be defined with a FQDN (fully qualified domain name) instead of &quot;localhost&quot;.</li>
    <li>Ensure that your target table is under the <tt>PBXT</tt> storage engine and has a <tt>LONGBLOB</tt> column (which must be nullable if you want to remove the BLOB reference from it).</li>
    <li>When you insert or update a row in this table, put a checkmark on the &quot;Upload to BLOB repository&quot; optional choice; otherwise, the upload will be done directly in your LONGBLOB column instead of the repository.</li>
    <li>Finally when you browse your table, you'll see in your column a link to stream your data, for example &quot;View image&quot;. A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time.</li>

    <p> 
        By clicking on the button 'toggle scratchboard' on the page
        where you edit x/y coordinates of those elements you can activate a
        scratchboard where all your elements are placed. By clicking on an
        element, you can move them around in the pre-defined area and the x/y
        coordinates will get updated dynamically. Likewise, when entering a
        new position directly into the input field, the new position in the
        scratchboard changes after your cursor leaves the input field.
    </p>
    <p>
        You have to click on the 'OK'-button below the tables to save the new
        positions.  If you want to place a new element, first add it to the
        table of elements and then you can drag the new element around.
    </p>
    <p>
        By changing the paper size and the orientation you can change the size
        of the scratchboard as well. You can do so by just changing the

        without interfering with the current placement of the elements.
    </p>
    <p>
        If ever an element gets out of range you can either enlarge the paper

    <a href="#faq6_30">6.30 Import: How can I import ESRI Shapefiles</a></h4>

    <p> 
        An ESRI Shapefile is actually a set of several files, where .shp file contains 
        geometry data and .dbf file contains data related to those geometry data. 
        To read data from .dbf file you need to have PHP compiled with the dBase extension

        <li>
            <p>
            Configure upload directory with 
            <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>, upload both

        </li>
        <li>
            <p>
            Create a Zip archive with .shp and .dbf files and import it. For this to work,

    <p> The Zoom search feature is an alternative to table search feature. It allows you to explore  
    a table by representing its data in a scatter plot. You can locate this feature by selecting
    a table and clicking the 'Search' tab. One of the sub-tabs in the 'Table Search' page is 
    'Zoom Search'. <br/><br/>

    Consider the table REL_persons in <a href="#faq6_6"><abbr title="Frequently Asked Questions">
    FAQ</abbr> 6.6</a> for an example. To use zoom search, two columns need to be selected, 
    for example, id and town_code. The id values will be represented on one axis and town_code 
    values on the other axis. Each row will be represented as a point in a scatter plot based 
    on its id and town_code. You can include two additional search criteria apart from the two
    fields to display.<br/><br/>

    You can choose which field should be displayed as label for each point. If a display
    column has been set for the table (see <a href="#faqdisplay"><abbr title="Frequently Asked 
    Questions">FAQ</abbr> 6.7</a>), it is taken as the label unless you specify otherwise.
    You can also select the maximum number of rows you want to be displayed in the plot by
    specifing it in the 'Max rows to plot' field. Once you have decided over your criteria,
    click 'Go' to display the plot.<br/><br/>

    After the plot is generated, you can use the mousewheel to zoom in and out of the plot.
    In addition, panning feature is enabled to navigate through the plot. You can zoom-in to
    a certail level of detail and use panning to locate your area of interest. Clicking on a
    point opens a dialogue box, displaying field values of the data row represented by the point.
    You can edit the values if required and click on submit to issue an update query. Basic
    instructions on how to use can be viewed by clicking the 'How to use?' link located just above
    the plot.</p>

    <a href="#faq8_1">8.1 Where can I get information about the security alerts issued for phpMyAdmin?</a></h4>

<p> Please refer to
    <a href="http://www.phpmyadmin.net/home_page/security.php">http://www.phpmyadmin.net/home_page/security.php</a>
</p>

<h4 id="faq8_2">
    <a href="#faq8_2">8.2 How can I protect phpMyAdmin against brute force attacks?</a></h4>

<p> If you use Apache web server, phpMyAdmin exports information about 
    authentication to the Apache environment and it can be used in Apache logs.
    Currently there are two variables available:
</p>
<dl>
    <dt><code>userID</code></dt>
    <dd>User name of currently active user (he does not have to be logged
    in).</dd>
    <dt><code>userStatus</code></dt>
    <dd>Status of currently active user, one of <code>ok</code> (user is 
    logged in), <code>mysql-denied</code> (MySQL denied user login),
    <code>allow-denied</code> (user denied by allow/deny rules),
    <code>root-denied</code> (root is denied in configuration),
    <code>empty-denied</code> (empty password is denied).</dd>
</dl>
<p>
    <code>LogFormat</code> directive for Apache can look like following:
</p>
<pre>
LogFormat "%h %l %u %t \"%r\" %>s %b \
\"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n"   pma_combined
</pre>
<p>
    You can then use any log analyzing tools to detect possible break-in
    attempts.
</p>

<h3 id="faqsynchronization">Synchronization</h3>
<h4 id="faq9_1">
    <a href="#faq9_1">9.1 How can I synchronize two databases/tables in phpMyAdmin?</a></h4>

<p> You can now synchronize databases/tables in phpMyAdmin using the Synchronize feature.
It allows you to connect to local as well as remote servers. This requires you to enter 
server host name, username, password, port and the name of the database. Therefore you can 
now synchronize your databases placed on the same server or some remote server.
</p>

<p>
This feature is helpful for developers who need to replicate their
database&#8217;s structure as well as data. Moreover, this feature not only
helps replication but also facilitates the user to keep his/her database
in sync with another database. Other than the full database, certain
tables of the databases can also be synchronized.
</p>

<p>
You need to fill in the host name of the server, the username and
password of an user account already there in MySQL. Port is by default
populated with 3306 (MySQL default port). Then the name of the database
should be mentioned at the end. All the information other than the port
needs to be filled explicitly for the source as well as target servers.
</p>

<p>
After successfully passing through the authentication phase, the source and
target database table names will be displayed. It will be a tabular
representation. 
</p>

<p>
On the left, are listed the source database table names. Some of the
names have a <code>+</code> plus sign preceding them. This shows that these tables
are only present in source database and they need to be added to the
target database in order to synchronize the target database. The tables
whose names are not preceded by a <code>+</code> sign are already present in the
target database. 
</p>

<p>
On the right, are listed the target database table names. There are few
table names that have <code>(not present)</code> appended after their names. This
means that these tables are to be created in target database in order to
synchronize target database with source database. Some table names
have a <code>-</code> minus sign preceding them. This shows that these tables are
only present in target database and they will remain unchanged in the
target database. The column in the middle shows the difference between
the source and target corresponding tables.
</p>

<p>
The difference is depicted by the red and green buttons with <tt>S</tt> and <tt>D</tt>
letters, indicating that either Structure or Data are not up to date. By
clicking on them, they will turn grey, what means that they will be synchronized.
</p>

<h4 id="faq9_2">
    <a href="#faq9_2">9.2 Are there problems with data synchronizing large
        tables?</a></h4>

<p>
Yes. This aspect of synchronization is currently limited to small tables, and they
must have a primary key.
</p>

<h3>Original Credits of Version 2.1.0</h3>

<p>
    This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
    to create a web-based interface to MySQL using PHP3. Although I have not
    used any of his source-code, there are some concepts I've borrowed from
    him. phpMyAdmin was created because Peter told me he wasn't going to
    further develop his (great) tool.
</p>
<p>
    Thanks go to
</p>
<ul>
  <li>Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
      code for the check when dropping a table or database. He also suggested
      that you should be able to specify the primary key on tbl_create.php3. To
      version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
      well as a bug-report. Plus many smaller improvements.
  </li>
  <li>Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
      were introduced in 1.3.0 (including quite significant ones like the
      authentication). For 1.4.1 he enhanced the table-dump feature. Plus
      bug-fixes and help.
  </li>
  <li>Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
      language-independent by outsourcing the strings to a separate file. He
      also contributed the French translation.
  </li>
  <li>Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
      tbl_select.php3, a feature to display only some columns from a table.
  </li>
  <li>Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
      functions in tbl_change.php3. He also added the
      &quot;Query by Example&quot; feature in 2.0.
  </li>
  <li>Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
      servers and is a regular contributor for bug-fixes.
  </li>
  <li>Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
      features for 2.0.6.
  </li>
</ul>
